I am curious about this as well. I had been feeding my dogs Nature's Variety Instinct kibble mixed with the canned version and they both look great. Their coats are like silk but Charlie still has tear stains. I just used that Groupon that someone posted about to buy two bags of Ziwipeak. I'm feeding that exclusively so I can see if that helps. It will also give me a chance to see how long a bag will last so I can decide if I can afford to feed that all the time.
I have a bottle of Angel Eyes but I'm going to wait before using it to see if the Ziwipeak makes a difference.
